Nowadays, computerized dimensional inspection is included in most manufacturing processes.Industrial vision systems, laser triangulation sensors (LTS) in particular, are responsible for ensuring dimensional and geometrical tolerance compliance.Computer-aided design / computer-aided engineering (CAD/CAE) plays an important role in the manufacturing process.However, in the design and engineering of LTS, there is no equivalent computer-aided tool to provide assistance to the process definition.This paper presents a simulation environment to assist with this issue.Based on the CAD files of the parts, all the parameters of an LTS sensor and its scanning strategy can be simulated in a virtual Direct3D environment.This simulation provides a re-creation of the camera acquisition, allowing collision and occlusion detection and ensures complete and effective digitalization.Furthermore, the capability of the process of tolerance compliance evaluation can be verified.Once the effectiveness of the process is proven, the simulation can be employed for continuous performance improvement and the incorporation of new parts.
